Trailer Inventory in Post Falls

Everything on the site is on this lot, new, and available to walk around today. What follows is the lineup with the sizes we stock and the one question that matters most in the Panhandle: how the trailer behaves loaded on a grade.

Enclosed cargo, 4x6 to 8.5x24

Enclosed models start at a 4x6 for a single motorcycle or a fixed kit and run to an 8.5x24 walk-in. The 6x12 is the volume seller. Anything running east into the Silver Valley or north to Sandpoint at weight wants tandem axles with brakes on both, because a sustained descent asks far more of a braking system than level running does.

Dump, 5 to 7 feet wide

Dump bodies in 5, 6 and 7-wide, 10-gauge steel floor and walls, powered lift both directions on a handheld control. Rock reaches the rating long before the body fills. Cold also strips capacity from a marginal battery, which is why a body that worked all autumn will not lift on the first hard morning.

Utility, 4x6 to 7x16

Open decks with mesh, solid or pipe-top sides. Firewood, brush, fence materials and gravel are the Panhandle staples, and the last of those decides the axle.

Equipment and tilt

Equipment trailers on Dexter axles with stand-up ramps for skid steers and compact tractors. Tilt decks from 10 to 22 feet load low-clearance machines in one movement rather than four.

Car haulers and powersports

Car haulers open or enclosed, tandem braked throughout. Powersports decks open or enclosed - sleds load fine on an open deck, but suits, helmets and fuel have nowhere dry to ride, which is what eventually sends most owners here indoors.

Buying and owning

Financing through Sheffield Financial and RockSolid Funding at fixed rates with no early payoff penalty, and Rent-to-Own through C3 Rentals with no hard credit check. Reserve online and we hold a specific trailer for seven days, which is worth doing from Sandpoint, the Silver Valley or across the state line. Parts counter and service bay on site, and two complimentary 40-point safety inspections at 12 and 24 months with every new trailer.

TrailersPlus is the only retail seller of Interstate Trailers; why Interstate has the construction detail. One of 92 locations, 11,900+ trailers network-wide, 4.8 from more than 10,000 reviews, 25+ years, roughly 95% USA-sourced weight.

Accessories and add-ons

Most of what people add later could have been specified at purchase for less. Tongue boxes, spare tire and carrier, security locks, tarp kits on dump bodies, E-track and tie-down systems inside enclosed trailers, high sides and mesh siding on open decks, and 24-inch side extensions where the load fills the deck long before it reaches the rating. All of it fitted here.

Interstate and Carry-On

We stock both. Interstate is exclusive to TrailersPlus at retail and covers the full range from the 4-wide up to the 8.5-wide. Carry-On sits alongside it on the utility and smaller enclosed sizes, at a different price point and specification. They are genuinely different trailers, and if you are choosing between them it is worth standing next to both rather than comparing two listings.

Reserving and collecting

A reservation holds one specific trailer for seven days. Worth doing from Sandpoint, the Silver Valley or across the state line, because stock here turns over faster than people expect. Book an appointment during that window and someone will walk the trailer with you, answer questions about the build, and sort the paperwork in one visit rather than two.

If nothing on the lot fits

Trailer Builder sets width, length, interior height, door configuration, GVWR and color to your own specification, typically six to eight weeks from order to collection. Builds run on proven standard configurations, which is what keeps both the quality and the lead time honest.
